    Avaliação e estimativa da receita bruta do café arábica e potencialidades de diversificação e expçoração de novos nichos de mercado como estratégia competitiva

    Objective: To analyze the agricultural policy of the national Arabica coffee and compare with the policies adopted by the major importers and estimate the Arabian gross revenue based on prices and national production. As well as researching problems of overproduction and high financing cost. Methods: It used data from Conab and Cepea / Esalq and Abic to form simple regressions for producer prices by state and national aggregate, applying the Kolmogorov-Smirnov adherence test. Estimated prices, they composed together with the production and the annualized gross monthly income through multiple regression for the main units of the federation as a management alternative level of government. Results: After the estimation of revenue, it was observed that prices behaved in the variability proposal as adhesion test. So the result of gross revenues, contributed to form, in a management capacity and production planning, an aggregate variable that makes up the development of production and prices of the producing states and Brazil. It has also noted that the typical positive and negative bienalidades culture throughout history have not increased the impact of coffee blockbusters. Another observation is that in periods of overproduction exporter of coffee sector was more active and equalized distortions of market prices. Final Thoughts: The variable gross revenue of Arabica coffee is measured at the aggregate level, for her the Brazilian government can be oriented both in search of an optimal level of production, expanding it or retracting. The Arabic culture with the exporter bias needs a policy for the domestic export sector so that culture not be so dependent on a single export product - the coffee green beans. Therefore, the government needs to pursue a policy of adequate credit and minimum prices, it is removing part of the cost of funding and allocate more investment funding resources in order to contribute to the coffee agribusiness, because with technical development, management and technological arise expansion potential of the consumer market for roasted and soluble coffee

    Consequences of prolonged caffeine administration and its withdrawal on pilocarpine- and kainate-induced seizures in rats
    (Blackwell Publishing, 2005-09-01) Hoexter, Marcelo Queiroz [UNIFESP]; Rosa, Pedro S.; Tufik, Sergio [UNIFESP]; Mello, Luiz Eugenio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Purpose: To investigate the consequences of caffeine consumption on epileptic seizures, we used the pilocarpine and the kainate models of epilepsy. We hypothesized that prolonged caffeine consumption or its withdrawal would alter adenosine levels and hence alter seizure susceptibility.Methods: We administered a 0.1% caffeine solution in the drinking water of adult male Wistar rats over a 2-week period. We challenged another group of animals with the same doses of pilocarpine or kainate 12 h after the withdrawal of the same caffeine-administration protocol.Results: This did not alter the threshold for the induction of seizures by a subconvulsant dose of pilocarpine (200 mg/kg, i.p.) or kainic acid (8 mg/kg, i.p.). Similarly, challenging another group of animals with the same doses of pilocarpine or kainate 12 h after the withdrawal of the same caffeine-administration protocol did not lead to any significant changes in seizures.Conclusions: With the pilocarpine model of epilepsy, we were not able to find any significant difference in seizure profile that could stem from either caffeine administration or its withdrawal. Despite the extensive laboratory evidence on the convulsant properties of xanthine derivatives in animal models of epilepsy, such strong evidence is lacking in clinical settings. Our current findings with the administration of caffeine at doses similar to those of daily life both support and confirm the clinical experience.

    Effects of cigarette smoke inhalation and coffee consumption on bone formation and osseous integration of hydroxyapatite implant
    (Instituto Internacional de Ecologia, 2013-02-01) Andrade, Ana R.; Sant'ana, Dcm.; Mendes Junior, Ja.; Moreira, Maria Eliza Castro; Pires, Gc.; Santos, Mp.; Fernandes, Geraldo Jose Medeiros [UNIFESP]; Nakagaki, Wilson Romero; Garcia, Jad.; Lima, Cc.; Soares, Ea.; Universidade José do Rosário Vellano; Universidade Federal de São Paulo (UNIFESP); Universidade Federal de Alfenas; Universidade Estadual de Campinas (UNICAMP); Universidade José do Rosário Vellano Faculdade de Medicina
    The present study aims to assess the effects of cigarette smoke inhalation and/or coffee consumption on bone formation and osseous integration of a dense hydroxyapatite (DHA) implant in rats. For this study, 20 male rats were divided into four groups (n = 5): CT (control) group, CE (coffee) group, CI (cigarette) group and CC (coffee + cigarette) group. During 16 weeks, animals in the CI group were exposed to cigarette smoke inhalation equivalent to 6 cigarettes per day; specimens in the CE group drank coffee as liquid diet; and rats in the CC group were submitted to both substances. In the 6th week a 5 mm slit in the parietal bone and a 4 mm slit in the tibia were performed on the left side: the former was left open while the latter received a DHA implant. As soon as surgeries were finished, the animals returned to their original protocols and after 10 weeks of exposure they were euthanised (ethically sacrificed) and the mentioned bones collected for histological processing. Data showed that exposure to cigarette smoke inhalation and coffee consumption did not interfere in weight gain and that solid and liquid diet consumption was satisfactory. Rats in the CC group showed a decrease in bone neoformation around the tibial DHA implant (31.8 ± 2.8) as well as in bone formation in the parietal slit (28.6 ± 2.2). On their own, cigarette smoke inhalation or coffee consumption also led to diminished bone neoformation around the implant and delayed the bone repair process in relation to the CT group. However, reduction in the bone repair process was accentuated with exposure to both cigarette smoke inhalation and coffee consumption in this study.
